Product Description

Product Description

 

Xanthan gum is an extracellular microbial polysaccharide produced by fermentation of sugars by Xanthomonas. Due to its special macromolecular structure and colloidal characteristics, it has many functions, such as emulsifier, stabilizer, gel thickener, sizing agent, film forming agent, etc., and is widely used in various fields of national economy.

Production Process

Process:

 

1. Preparation of strains: After the strains are activated in the seed room by the inclined plane and cultivated in the shaker flask, the seeds are moved to the first-level seed tank for expansion cultivation. After a period of cultivation, they are moved to the second-level seed tank for expansion cultivation.

2. Fermentation: After the strains are graded in the seed tank, they are inoculated into the fermentation tank, aerated and stirred at 30°C, and the fermentation time is 48~60h.

3. Fermentation broth treatment: Pretreatment by filtration and ultrafiltration concentration method removes bacterial cells and various insoluble impurities, so that the xanthan gum no longer contains active bacterial cells, insoluble impurities and pigments that affect product quality, etc., and Concentrate the fermentation broth;

4. Precipitation reaction: add water-soluble organic solvent ethanol, etc. and let it stand for about 6 hours to precipitate xanthan gum.

5. Elution and dehydration: the xanthan gum obtained by precipitation was eluted by adding alcohol, and the elution period was 4 hours; the eluted xanthan gum was dehydrated by an automatic disc centrifuge.

6. Drying: After elution and separation, the water content is about 18%. After drying with a vacuum dryer, the water content is reduced to 13%. The drying speed is fast and the temperature is low, which can ensure the production quality.

7. Crushing and packaging: The dried xanthan gum is crushed and sieved by a pulverizer, and then packaged to obtain the finished xanthan gum. 8. Ethanol recovery: the waste ethanol used for elution is distilled in the distillation column and then re-entered into the system for use.

Food grade

Xanthan gum used in baked goods (bread, cakes, etc.) can improve the water retention and softness of baked goods during baking and storage to improve the taste of baked goods and prolong shelf life;

It has the function of thickening and stabilizing food structure in frozen food;

Adding xanthan gum to jam can improve the taste and water holding capacity and improve the quality of the product;

The compound of xanthan gum with carrageenan and locust bean gum is also commonly used in jelly and candy processing.

Industrial grade

Xanthan gum is specially produced as mud additive for oil drilling. Being an environment friendly and high efficiency mud additive, it has an excellent tolerance to a wide range of temperature, pH and salinity. It can extremely increase the mud penetrative rate and suspension ability to the drilling-cuttings. Meanwhile, it can also reduce the pressure loss during drilling, stabilize the well-bore, prevent the damage to oil formation, and improve the efficiency of drilling, work-over and completion.
